hello everyone, very new to this, I would like to know how to update my daughters nuvi 1300 to the latest city navigator europe nt map please. I'm starting from scratch!!! many thanks

Any chance for torrent?

Can someone show me the way to make a Nuvi 765 up to date again?

Current maps are, according to the map info screen:
CN Europe NT 2015.20 3D &
CN Europe NT 2015.20 [1] BeNeLux

Have no idea about firmwareversion, did not find it in the short time I had the device in my hands.

Do I need to update the OS/Navcore/Firmware?
Wich map is the most detailled and recent for the device wich will fit for Europe (or part of it)?

Thanks in advance for any help!

Thanks!
I have SD-cards lying around in all sizes from 2-32GB, so space shouldnt be a problem. The 2 *.jcv-files you are referring to, are they for a specific region?

A 4 GB SD should be optimal for your needs, 8 GB if you want to Upgrade to Full Europe.
The 2 JCVs are both referring to entire Europe
D2504280A.jcv 690 MB is the Large one (it contains more images), better to use if space isn't a problem
D3084250A.jcv 326 MB is the Small one (it contains less images)

Thanks for the quick response and detailled answers, GarmanNuvi & FireFox58.

That was an easy upgrade, even for a "Garmin noob" like me. The firmware was already 4.50, so that saved me the hassel of installing the Garmin Express software.
The files:
gmapsupp.img + gmap3d.img + D2504280A.jcv
together, are 5,55GB and after putting them on a FAT32 16GB Class10 SD-card in a directory "Garmin" the map was recognized without any hassel.
To be sure my friend uses the "right" map, I removed those files from the internal memory.

All works fine. Thanks again.

Hello, I'm trying to update the map on a garmin nuvi 1300, it's running (up to date) software version 6.30, but (out of date) map version CN Europe NT 2010.20 [1] UK & Ireland, and help would be greatly appreciated. Hopefully an idiots guide on how to get this done if possible, it's obviously an older system from around 2010 which I'm trying to update for other family members to use, by system memory or SD card, to the latest (up to date) map version please. Thank you, FeSTeRphil.

I understand what you have said but I cannot find the system file or any of the file names you mention on here, what am I doing wrong as this is driving me crazy. Please can you explain a little clearer, literally like an IDIOTS guide on how to do this, and any more information you need please just ask, I am willing to update the system memory, or an sdcard, could you explain both methods, is it possible my garmin nuvi 1300 is locked, is that even a thing, is it possible to just replicate what garmin would do and update this thing without being ripped off, this has ruined my weekend !!!! .. thank you, FeSTeRphil.

Hello guys,
can someone tell me install instructions for Zumo 500?
Thnks
